Red lines on your nails are known as longitudinal erythronychia. They can be indicative of a number of underlying conditions, including vasculitis, which can impede blood flow and cause tissue or organ damage, and scleroderma, a connective tissue disorder that causes the skin to thicken and harden.

Longitudinal erythronychia (red lines)
Red lines on the nail are known as longitudinal erythronychia. They are one of three basic types of nail lines, the other two being white lines (leukonychia striata) and brown-black lines (longitudinal melanonychia). Nail lines are a common presenting finding and can be indicative of underlying systemic diseases. Longitudinal erythronychia can be caused by vasculitis, which impedes blood flow and causes tissue or organ damage. It can be triggered by infection, medications, and cancers. It can also be caused by scleroderma, a connective tissue disorder that causes the skin to thicken and harden. In children, it can be caused by a disease that causes inflammation and bleeding of small blood vessels, commonly affecting the skin, joints, intestines, and kidneys.

Underlying systemic diseases
Red lines on the nails, known as longitudinal erythronychia, can be indicative of underlying systemic diseases. The nail unit includes the nail matrix, the lunula, the nail fold, the nail plate, and the nail bed. The nail bed lies under the nail plate and on top of the distal phalanx and extends from the lunula to just proximal to the free edge of the nail. Its rich blood supply gives it its reddish colour.
Red lines on the nails can be caused by a disease that causes inflammation and bleeding of small blood vessels, commonly affecting the skin, joints, intestines, and kidneys. This can lead to rashes, stomach pain, and kidney damage. Though it can affect anyone, it is more common in children under 10 years old. The cause is not well understood, but it may result from an immune system issue.
Vasculitis is another potential cause of red lines on the nails. It can impede blood flow and cause tissue or organ damage. There are many different types of vasculitis, each with its own triggers, including infection, medications, and cancers.
Scleroderma, a connective tissue disorder that causes the skin to thicken and harden, is another possible underlying systemic disease that can cause red lines on the nails. It may also affect other organs.

Vasculitis
Red lines on your nails, known as longitudinal erythronychia, can be caused by vasculitis.

The cause is not well understood, but it may result from an immune system issue. Vasculitis can impede blood flow and cause tissue or organ damage.

Scleroderma
Red lines on your nails, known as longitudinal erythronychia, can be indicative of a number of conditions. One such condition is vasculitis, which can impede blood flow and cause tissue or organ damage. There are many different types of vasculitis, each with its own triggers, including infection, medications, and cancers.
The nail unit includes the nail matrix, the lunula, the nail fold, the nail plate, and the nail bed. The nail matrix is responsible for nail plate production and extends from under the proximal nail fold to the lunula, the half-moon-shaped area at the base of the nail. The nail bed lies under the nail plate and on top of the distal phalanx, and its rich blood supply gives it a reddish colour.
A thorough inspection of the fingernails and toenails is an integral part of a complete physical examination. An understanding of basic nail anatomy and the different types of nail lines can help clinicians diagnose and treat nail disorders and recognise underlying systemic diseases. For example, transverse white nail lines, or Mees lines, have been associated with acute systemic stress, such as from heart failure or breast cancer.

Immune system issues
Red lines on your nails, known as longitudinal erythronychia, can be indicative of a range of underlying health issues. One possible cause is vasculitis, a condition where the body's immune system attacks blood vessels throughout the body, causing inflammation and impeding blood flow. This can lead to tissue or organ damage. Vasculitis can be triggered by a variety of factors, including infection, medications, and cancers.
Another potential cause of red lines on the nails is scleroderma, a connective tissue disorder that causes the skin to thicken and harden. Scleroderma may also affect other organs. While the exact cause of scleroderma is unknown, it is believed to be the result of an immune system issue.
It is important to note that an understanding of basic nail anatomy and the different types of nail lines can help clinicians diagnose and treat nail disorders, as well as recognize underlying systemic diseases. Therefore, if you notice any unusual changes in your nails, such as red lines, it is recommended to consult a healthcare professional for a thorough evaluation.
